Abstract

The utility model relates to a driving and locking device of a gate, which comprises a speed changing box and a motor. Two pairs of wheels are fixed respectively on two rolling shafts and are tightly contacted with a pair of rails, one gear is fixed on each rolling shaft, the other gear is combined with the speed changing box and is engaged with other two teeth so that the motor drives the gears and the wheels to rotate, the three gears engaged with each can apply downward force to the wheels so that the wheels are tightly contacted with the rails to move without generating idle rotation. The tail end of one of the rails is erected with a backstop which can be engaged with one of the gears so that a gate is not easy to push.

Description

Driving device of gate

The utility model relates to a kind of big door drive, refers to especially a kind ofly can effectively drive gate also can be used for simultaneously the locking device at gate.

General gate, retractable door for example shown in Figure 1, the cylinder 50 that comprises multi-section type can be provided with some and sheave and 51 can be erected at slidably on the track 52 in its bottom, can be bound up for these cylinders 50 are and be provided with some cross-like connecting rods 53 between these cylinders 50 telescopicly; End in this retractable door mostly is provided with a driving mechanism, so that be used for opening or closing this door; This driving mechanism is please referring to Fig. 2 and shown in Figure 3, comprise that a base plate 54 is fixed to the bottom of cylinder, one gearbox 55 and a motor 56 are erected at this above base plate, one sprocket wheel 57 links to this gearbox 55, and drive another sprocket wheel 59 by a chain 58, and sprocket wheel 59 is fixed on the axle center 61 of one wheel pairs 60, makes this can be driven and rotate by motor 56 wheel 60, and then drives the gate and advance or retreat; Yet this big door drive mechanism has following shortcoming in the use:

(1) this chain 58 has the power that sprocket wheel 59 is up drawn when driving sprocket wheel 59, wheel 60 is had by the tendency of up drawing and de-orbiting, so be easy to produce the phenomenon that dallies and skid between wheel and the track, especially on rainy day, this situation is especially serious, uses quite inconvenient.

(2) in addition, when retractable door was pulled near closed condition, forked connecting rod 53 had one with the past pulling force of pulling back in gate, so the time near the fastening position place, wheel also can be easy to skid, and must go by user's manpower to promote just can shut, and is quite inconvenient.

(3) wheel 60 only is slidingly installed in above the track 52, so move to the position of closing and when not utilizing lockset that it is locked, as long as anyone promote this gate gently can open the gate easily when door, this equals not have door the same, has no the sense of security.

The purpose of this utility model is to provide a kind of device that can drive the gate effectively and also have locking gate effect.

The purpose of this utility model is achieved in that promptly provides a kind of gate to drive and locked instrument, and it comprises that a gearbox and a motor are fixed on the bottom of this gate one end, and a pair of first wheel is fixed on one first roller bearing and is close to pair of tracks; It comprises that also a pair of second wheel is fixed on second roller bearing and is close to this on the track, one first gear is fixed on this first roller bearing, one second gear is fixed on this second roller bearing, and one the 3rd gear be bonded to this gearbox and and this first gear and this second gear be meshed, make this motor can order about this first gear and the rotation of this second gear, and the downward power that applies is to above-mentioned wheel, can order about above-mentioned wheel and be close to track and move, make this wheel be unlikely the phenomenon that produces idle running.

Described big door drive, wherein the end at a track sets up a backstop, and this backstop comprises that at least one tooth can be meshed with this second gear, makes this gate to be promoted easily.This backstop inside preferably also is provided with a groove, can supply ccontaining this second gear, makes this second gear can firmly be remained in the place, location.

Device of the present utility model has the following advantages:

(1) gear or the chain that links to gearbox can apply a downward strength to wheel, makes the gate be unlikely upwards to de-orbit and can firmly be adjacent to track, can advance effectively or retreat.

(2) it has a locked instrument, makes door when moving to fastening position, and this gate can't be opened easily and can reach the effect that closes door really.

(3) two-piece type backstop can firmly fasten rotating shaft, and is fixed on this gear above rotating shaft and can be meshed with the tooth of backstop bottom, makes the gate firmly to be maintained in its closed position.

For further specifying structure of the present utility model, feature and operation thereof, below in conjunction with description of drawings, wherein:

Fig. 1 is the position body schematic diagram of traditional retractable door;

Fig. 2 is the schematic perspective view of the driving mechanism of traditional retractable door;

Fig. 3 is the end-view of traditional drive mechanism of telescopic door;

Fig. 4 is the stereogram of the utility model device;

Fig. 5 is the end-view of the utility model device;

Fig. 6 is the operation chart of drive gear set of the present utility model;

Fig. 7 is the operation chart of the utility model device;

Gate of the present utility model drives and locked instrument, see also Fig. 4 and shown in Figure 5, comprise that mainly a base plate 10 is fixed on the place, bottom of gate 30 1 ends, one gearbox 11 and a motor 12 are erected at this above base plate, two pairs of wheels 13,14 are separately fixed at two roller bearings 15, on 16 and can rollably be supported on two tracks 17, each fixes a gear 18 on each roller bearing, 19, and gear 20 be bonded to this gearbox 11 and and this two

gear

18,19 are meshed, wherein this two roller bearing 15,16 utilize carriage 21 grades can be bonded to this base plate 10 places (Fig. 5) rotationally.

Please referring to Fig. 6, when being driven by motor 12, gear 20 rotates, for example be when counterclockwise rotating, it can order about two

other gear

18,19 are clockwise direction rotates, and make wheel 13,14 can drive the gate advances or retreats, wherein must be noted that, this gear 20 has a kind of with the past power that presses down of two other gear, so this power can be with roller bearing 15,16 and wheel 13,14 down compress into and can very firmly contact track 17, make the gate to be driven effectively to move and do not have a phenomenon of slip, and general legacy drive has the strength that sprocket wheel and wheel are up drawn, so that traditional gate produces the situation of sliding is more common.

In addition please referring to Fig. 4 and Fig. 7, set firmly a backstop 22 on the track 17 therein, these backstop 22 inside have a groove 23 can supply ccontaining gear 18, then being provided with at least one tooth 24 can be meshed with this gear 18 in the bottom of this groove, make when this gate moves to fastening position, these gear 18 meetings and this tooth 24 are meshed and can't be separated from, so can not promote the gate this moment.
